Abc bookstore sells new books, n, for $12, and used books, u, for $8; and magazine, m,for $5 each. the store sold 5 more used books than new books, and twice as many magazines, new books, and old books did abc bookstore sell?

a. n=12; u=14; m=7
b. n=12; u=8; m=5
c. n=14,u=12; m=7
d. n=7; u=12; m=14

Use addition and subtraction to simplify the following polynomials. a. add polynomials: (3 – 4x + 8x^2) + (–6 + 2x – 5x^2) step 1: rewrite the polynomials without the parentheses. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial. b. subtract polynomials: (3x – 5 – 7x^2) – (–2 + 6x^2 – 5x) step 1: rewrite the polynomials without the parentheses. remember to multiply each term in the second parentheses by –1. show your work. step 2: write the polynomial in descending order and use parentheses around like terms. step 3: add the like terms identified in step 2 to simplify the polynomial.
